中文摘要	生物土壤结皮(biological soil crusts,BSC)在荒漠植被的恢复及稳定性维持方面发挥了重要作用,被誉为荒漠生态系统工程师。BSC微生物群落是其发挥功能的主要成分,参与了BSC的形成、土壤性状的改善、土壤团聚体的稳定及植被的发育等过程。由于技术方法的限制,以往对BSC微生物群落发育如何调控荒漠植被稳定性的机理尚不清楚。近年来,随着土壤微生物组学技术的快速发展,BSC微生物群落组成及其功能的研究取得了较大进展,关于BSC微生物群落对荒漠生态系统贡献的认识日渐清晰。本文总结了温带荒漠BSC演替过程中微生物不同类群细菌、真菌、古菌群落的组成结构及参与碳氮循环的潜在功能变化,并对影响微生物群落结构和功能的土壤因素进行了剖析,阐释了BSC微生物群落与土壤功能性状相互作用及协同演替的模式,厘清了BSC促进荒漠土壤改善的机理,为温带荒漠植被恢复及荒漠生态系统对全球贡献的理解提供了依据。
英文摘要	Biological soil crusts (BSC), known as desert ecosystem engineer, play an important role in the restoration and stability maintenance of desert vegetation. BSC microbial communities are the main components of their functions. They participate in the formation of BSC, the improvement of soil physiochemical properties, the stability of soil aggregates and the development of vegetation. In the early stage, due to the limitation of technical methods, the mechanism of how BSC microbial communities regulate the stability of desert vegetation is unclear. However, with the rapid development of soil microbiome technologies in recent years, the research on the composition and function of BSC microbial communities has made great progress, and the contribution of BSC microbial communities to desert ecosystem has a clearer understanding. In this paper, the compositional structure of bacterial, fungal and archaeal communities and their potential functional changes in the carbon and nitrogen cycles during BSC succession in temperate desert are reviewed. Additionally, the soil environmental factors affecting the structure and function of microbial communities are summarized, and the successional model of interaction between different BSC microbial groups and soil physiochemical properties is explained. These results help us to clarify the mechanism of BSC promoting the improvement of desert soil conditions, and to provide theoretical basis for understanding the restoration process of desert vegetation and the contribution of temperate desert ecosystems to the world.
